Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Anchovy Egg Sauce
Ingredients
Directions
In a saucepan, melt the butter and stir in the flour to form a roux.
Add the anchovy paste and milk, stirring steadily to remove lumps.
Cook until the sauce is smooth and thick.
Stir in the minced egg and cayenne, then serve warm.
For a richer sauce, add thick cream before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the roux and carries flavour into the sauce.
- Flour
- Thickens the milk into a smooth sauce when cooked with the butter.
- Milk
- Forms the liquid base that the roux thickens into a sauce.
- Hard-boiled egg
- Adds body and a soft, savoury texture to the sauce.
- Anchovy paste
- Adds a salty, savoury depth that defines the sauce's flavour.
The step that matters
Stirring the milk into the roux. Adding liquid steadily while stirring keeps the starch dispersed so the sauce cooks smooth rather than lumpy. Lumps form when starch clumps before it can hydrate evenly.
